Joel Sartore is a man on a mission – to photograph 12,000 species of mammals, amphibians, birds, insects and other species before they go extinct, through a project he callsPhotoArk. Green News Update will present a feature story on Sartore and PhotoArk – now 10 years on –on his new book Rare, and a current exhibition of the PhotoArk project at the National Geographic Museum in Washington DC. See more of Joel’s photos in our post on Chasing Extinction.
